I've had the 006 over a year now and know exactly how to get what I want from a shot, superb camera! I've had the 007 for a few weeks and getting to know it better, I know a couple of people have asked about the differences at base ISO between the 2 cameras so as LR has now updated to include support for the 007 I thought I'd have a play and see what's what.
Please bare in mind I am a commercial photographer, I am not a professional tester, I don't care for it beyond getting to know a camera and how it fits to my own needs, my observations are based on how I work and what I want from a file, it may be helpful, it may not, please take anything I write as it is intended. You may not like what I like or work as I work so it's just what it is!
I have shown some high ISO shots, the 007 is the best camera I have used at ISO 800/1600 and has allowed me to get better aurora/night shots than any other camera I have tried. What I wanted to look at was what was happening at lower ISO's and whether that magic from the 006 has been lost in the move to CMOS.
I had a wander around my garden to take a few shots, what I am looking at here is the overall image, I'm not expecting any difference in sharpness, depth of field etc. just wanted to see if the "look" of the image would be similar. These are not controlled conditions, light changing etc. so the images are not captured in exactly the same light but they are same camera settings, same lens and mounted on a tripod. This is not art it's 10 mins in my garden at -2! Obviously nothing can be judged from a jpeg on the interweb so you'll have to take my word for the conclusions, I'm only adding the shots here as it would be boring just reading my text!
Dark shadow conditions..
Brighter backlit conditions and dark shadows.. focussed in different places but I'm looking at overall image feel not specifics!
Not very exciting I know but it's clear from the original files that there is very little difference, they do not process the same, white balance is different for one, you can't process one and copy to the other, wildly different if you do that. Printing 007 files at ISO 800 and they look completely amazing on my ipf6400 at 24 x 36, I can't print bigger here. I feel any differences are down to processing rather than what the camera is capturing.
I have taken to keeping wides on the 006, mainly because if I'm shooting landscapes I will tend top use a tripod, base ISO etc. and putting the 180 on the 007, walking around and portraits etc. the higher ISO is absolutely brilliant! A couple of portraits from last week (I haven't processed these in the updated LR so these are pre LR support) with the 007 at ISO 800..
And one at ISO 1600.
This may not give much info to most of you but maybe a few will find it interesting, nothing better than handling a camera and shooting what you like with it to help make your own mind up. For me, I will use either camera in normal conditions and the 007 in low light and be happy with files from both.
